Machined from submicron-grade solid carbide, it delivers superior wear resistance and edge retention compared to standard carbide grades. The bar has a minimum bore diameter of 0.23 inches and a maximum bore depth of 1.2 inches, with a shank diameter of 5\/16 inches and an overall length of 2.5 inches. The bright finish reduces friction and built-up edge during cutting. Machinists and tool-and-die professionals reach for this bar when dimensional accuracy and surface finish quality are critical in small-bore applications.\u003c\/p\u003e\u003cp\u003eThis boring bar is suited for precision internal boring in ferrous and non-ferrous materials across job shop, production machining, and toolroom environments. The right-hand cutting direction makes it compatible with conventional lathe spindle rotation. A corner radius range of 0.005 to 0.008 inches provides a controlled blend at the bore floor, reducing stress concentrations in finished workpieces. It is appropriate for tight-tolerance bores where chatter control and rigidity matter, particularly in small-diameter work where carbide rigidity outperforms high-speed steel alternatives.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSubmicron solid carbide construction for extended tool life and consistent edge geometry\u003c\/li\u003e\n\u003cli\u003eMinimum bore diameter of 0.23 inches suits tight internal features\u003c\/li\u003e\n\u003cli\u003eMaximum bore depth of 1.2 inches allows reach into moderately deep bores\u003c\/li\u003e\n\u003cli\u003eCorner radius of 0.005 to 0.008 inches reduces stress risers at the bore floor\u003c\/li\u003e\n\u003cli\u003eBright finish coating minimizes friction and chip adhesion\u003c\/li\u003e\n\u003cli\u003eRight-hand cut configuration for standard lathe spindle rotation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style solid carbide boring bar for use in standard boring bar holders accepting a 5\/16-inch shank diameter on CNC lathes and manual turning centers.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified machinists following shop safety procedures. Power down and lock out the machine spindle before securing or changing tooling. Ensure the shank is fully seated and clamped in the boring bar holder with appropriate torque per the holder manufacturer's specification. Verify bore diameter and depth settings with calibrated gauging before running production cuts.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBoring Bar Type\u003c\/strong\u003e: Corner Radius\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Bore Diameter\u003c\/strong\u003e: 0.23 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Bore Depth\u003c\/strong\u003e: 1.2 inches (1-13\/64 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 5\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.005 to 0.008 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Submicron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish Coating\u003c\/strong\u003e: Bright\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.125 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: ACCUPRO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: B2301200R\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51739514175794,"sku":"B2301200R","price":60.16,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b6cd07c27c8420bde2aad8cc36a1410e.jpg?v=1788815521","url":"https:\/\/voomisupply.com\/products\/accupro-b2301200r-corner-radius-boring-bar-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
